In IVF-ET, embryo is typically transferred at which stage to the uterus?
Select the correct option:
Solution
Incorrect! Answer:
Blastocyst
- IVF-ET: In Vitro Fertilization followed by Embryo Transfer.
- Stages of Transfer:
- ZIFT (Zygote Intra Fallopian Transfer): Zygote or early embryo (up to 8 blastomeres) is transferred into the fallopian tube.
- IUT (Intra Uterine Transfer): Embryos with more than 8 blastomeres are transferred into the uterus.
- Advanced Success: While IUT can happen at the morula stage, modern clinical practice often targets the Blastocyst stage for uterine transfer because it mimics the natural timing of entry into the uterus and allows for better selection of the healthiest embryos.
